  Tripeptidyl-peptidase II (TPP II) inhibitory activity of ( S )-2,3-dihydro-2-(1 H -imidazol-2-yl)-1 H -indoles, a systematic SAR evaluation. Part 2

  摘要：

  We have systematically explored the structure-activity relationship (SAR) for a series of compounds 2 as inhibitors of tripeptidyl-peptidase II (TPP II), a serine protease responsible for the degradation of cholecystokinin-8 (CCK-8). This SAR evaluation of the core structure 2 suggest a fairly restrictive pharmacophore for such related structures, but has yielded a limited set of compounds (2b, 2c, 2d, 2s, and 2t) with potent TPP II inhibitory activity (IC50 4-11 nM).

  Design, Synthesis, and Tripeptidyl Peptidase II Inhibitory Activity of a Novel Series of (S)-2,3-Dihydro-2-(4-alkyl-1H-imidazol-2-yl)-1H-indoles

  摘要：

  Butabindide, 1, was previously reported as a potent inhibitor (IC50 = 7 nM) of the serine protease enzyme tripeptidyl peptidase II (TPPII), an endogenous protease that degrades cholecystokinin-8 (CCK-8). We found that 1 has some inherent chemical instability, yielding diketopiperazine 2 fairly readily under mimicked physiological conditions. We therefore prepared imidazoles 3, which are void of 1's inherent instability, and have found that our novel analogues maintained comparable TPPII inhibitory activity (e.g.,for 3c, IC50 = 4 nM) as 1.
